(Usa), Inc. - **Product Code:** [HWC](/submissions/OR/subpart-d%E2%80%94prosthetic-devices/HWC.md) - **Decision Date:** Mar 4, 1996 - **Decision:** SN - **Submission Type:** Traditional - **Regulation:** 21 CFR 888.3040 - **Device Class:** Class 2 - **Review Panel:** Orthopedic - **Attributes:** Therapeutic ## Intended Use Transposition of Anterior Tibial Tuberosity. Possibility of compression without adding any washer. ## Device Story Single-use, permanent internal bone fixation screw; flat-headed, partially threaded design; used without washer for tibial tuberosity transposition; provides compression; available in 40-60 mm lengths; implanted by orthopedic surgeons in clinical/OR settings; stabilizes bone segments to facilitate fusion. ## Clinical Evidence No clinical data provided; device relies on established material properties and mechanical design equivalence to predicate devices. ## Technological Characteristics Material: Titanium alloy Ti6Al4V ELI per ASTM F136-92 or ISO 5832-3-90. Form factor: Flat-headed, partially threaded screw. Sizes: 40, 45, 50, 55, 60 mm. Energy source: None (mechanical). Sterilization: Not specified. ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - Partially threaded bone screw (Howmedica, Inc.) - Partially threaded bone screw (Synthes) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
